Volvo B5254T Inline-5 Turbo Engine

Volvo's B5254T is a 2.5-litre turbocharged inline-five that defined Volvo's performance identity in the 1990s and 2000s. It powers the 850 T5-R (240 hp), V70R (300 hp), and C30 T5 (230 hp) — three different generations of Volvo performance car sharing the same fundamental five-cylinder architecture. The B5254T's combination of five-cylinder smoothness, robust bottom end, and scalable turbocharger made it a favourite for aftermarket tuning, with 500+ hp possible on the stock block.
